US study shows updated COVID vaccines cut hospitalization odds by 55%

The 2025-2026 COVID-19 vaccines were associated with 50% estimated effectiveness against COVID-19-associated emergency department and urgent care encounters among immunocompetent US adults. They were also linked to an estimated 55% effectiveness against COVID-19-associated hospitalization, providing added protection beyond existing immunity from prior infection or vaccination.

Study links COVID-19 to higher sleep apnea risk years after infection

Researchers analyzed more than 910,000 adults and found that SARS-CoV-2 infection was associated with a higher adjusted risk of new-onset obstructive sleep apnea up to 4.5 years later. The association appeared in both hospitalized and non-hospitalized COVID-19 patients, supporting targeted screening in higher-risk post-COVID groups while highlighting the need for objective sleep testing.

Common genetic difference may increase the risk of severe COVID-19 and lung fibrosis

A genetic difference carried by nearly one in three people may increase the risk of severe COVID-19 and lung fibrosis by disrupting the function of a previously unknown protein, according to a new study.

50-year review shows global Ebola spread remains rare despite outbreak fears

Researchers reviewed Ebola disease cases outside Africa from 1976 to May 2026 and found only 28 confirmed epidemic-linked cases, most involving medical evacuation or occupational exposure. Only four latent travelers were diagnosed after border screening, suggesting that undetected intercontinental spread remains rare when outbreaks are controlled at source.

Using the mathematics of quantum mechanics to improve neuroblastoma outcomes

For a child diagnosed with neuroblastoma-the most common infant cancer, occurring when early nerve cells grow out of control-the path to treatment isn't simple.

Bogotá’s strictest COVID restrictions delivered the clearest air-quality gains

A natural quasi-experiment in Suba, Bogotá, found that more stringent COVID-19 mobility restrictions were associated with larger reductions in PM₁₀ and PM₂.₅ air pollution. The findings suggest targeted traffic and emissions controls could improve urban air quality, although ozone responses were more complex, and the results may not generalize beyond this high-traffic district.

US adults are taking more supplements as multivitamins lose ground

A 25-year NHANES analysis of 63,442 US adults found that reported dietary supplement use rose from 51% to 60%, with the largest increases among adults aged 65 years and older. Use shifted away from multivitamin-multimineral products and toward vitamins, minerals, botanicals, and nonvitamin nonmineral supplements marketed for immune, anti-inflammatory, gut, skin, and joint health.

Tiny genetic change influences coronavirus spillover into humans

Most pandemics start when a pathogen spreads from animals to humans. It's a leading explanation for the COVID-19 pandemic: the SARS-CoV-2 virus, which causes COVID-19, is a cousin to coronaviruses that live in bats.

Global study links rising obesity to premature heart disease deaths

Researchers are warning that obesity is reshaping the global cardiovascular disease crisis, as trend data covering 204 countries reveal that heart disease now peaks in people aged 50-54 rather than the elderly and increasingly in South Asia, where rates have grown more than three times faster than global averages, according to a study being presented Monday at ENDO 2026, the Endocrine Society's annual meeting in Chicago, Ill.

Dual-target CAR T therapy triggers broad immune response in brain cancer

Dual-target CAR T cell therapy for recurrent glioblastoma (GBM), delivered directly into the cerebrospinal fluid (CSF), triggers a broad immune response, with natural killer (NK) cell activation linked to better patient outcomes and longer overall survival.

New EHR-based marker flags transplant patients at high risk for organ rejection

A new multicenter study led by researchers at the Icahn School of Medicine at Mount Sinai suggests that a novel electronic health record-based marker can help clinicians identify transplant patients at high risk for organ rejection due to not taking their medications as prescribed-and intervene before the rejection happens.
